The present invention is concerned with the provision of asewing machine attachment of the generalcharacter disclosed in the I prior patent of Samuel Halberg, No. 1,607,532

l dated November 16, 1926., The patented device included means for supporting a roll of tape or the likeadjacent asewing machine for guiding the tape under the needle of the machine and forselectively manually severingthe tape at any time.

In accordance with. he present invention the construction of the attachment has been materially improved. In the first 'place, the entire, attachment is now provided with 4, means for holding it securely against vibration in use. The construction of the tape roll holder has been improved to permit the ready insertion of a tape rollinto the hole The tape cutter mechanism has been rendered much more positive and accurate, and means has been provided for preventing anyretrograde movement, of the tape at any time. With the old machine a certain amount of back lash sometimes developed in the .tape

, roll which would cause the free end of the I standard 14 and is adapted to carry the tape tape to slip back after it had been settled.

Other objects of. the present, invention are to provide a sewing machine attachment. of simple, practical construction, which will be ru ged, durableandefficient in use, well suited to the requirements of economical fmanufacture, convenient manipulation and ready attachment to,.or removal from a sew ing machine.

'.... Nith the abovev noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as willbe more.

fully hereinafter set forth and. pointed out in the claims. The invention may bemore fully understood from the following description in connection with the accompanying drawings, wherein chine showing our improved attachment in appl ed position.

Fig. 4 is a transverse sectional view on'the' line 4-4 of Fig. 3. I

Fig.5 is a top plan view, of the tape guide.

Fig. 6 is av longitudinal sectional view therethrough on the line 66 of Fig. 5.

Fig. 7 is a detail showing the arrangement" of the gauge plate relatively to the needle and presser foot. i

In the drawings we have used the reference numeral 10 todesignate generally a sewing. .machine of conventional construction including the usual arm 11, head 12 and needle plate 13. This sewing machine is adapted to be mounted on a table or other suitable support, and the attachment of the present invention is supported partly by the machine and partly by the table in order that vibration may be reduced to a minimum.

A generally L-shaped bracket includes a vertical standard 14 formed at its lower end with afoot 15 adapted to be screwed or otherwise rigidly secured to the table (not shown) which supports the sewing machine. The horizontal arm 16'ofthe L-shaped bracket projects at right angles from the top of the,

roll holder, best seen in Figs. land 2.

V The tape roll holder includes a'stationary bracket 17 rising fronithe arm 16 and carrying a stationary plate 18 upon which is mounted a hub 19 for the tape roll 20. Preferably, the hub 19 is adjustably carried on a screw 21 projecting through the bracket 17 and plateg18; this screw being held against rotation by a spring finger 22 entering a notch inthe screw head. Cooperating with the plate 18 to constitute the open sided tape roll holder is a plate 23 hingedly mounted as at 23' for pivotal movement about its lower edge. Preferably thehinge'23' is aspring hinge so that the plate 23 will automatically be restored tothe illustrated vertical position to permit application or removal of the tape roll20. I p

- A tape guiding member, cut, stamped and bent from a singlestrip of metal or otherwisesuitablv vformed includes a horizontal ortion whichwe have designated generally by the reference numeral24, and a vertical portion indicated generally at 25. One end of portion 24 of the tape guiding unit is secured as at 26 to the arm 16, while the intermediate portion of the member 24 is secured to a bracket 27 which in turn is fixed to the arm 11 of the sewing machine by a U-bolt 28 encircling the arm. Thisbolt 28 may incidentally serve'to clamp one end of a bracket arm 29 integral with the vertical portion 25 w of the tape guiding unit.

The free end of the tape being led from the tape roll 20 is first passed under astrap 3O afiixed to the portion 24 of the tape guide. Strap 30 preferably defines with the tape guide member 24 a channel for the tape, the

tape being additionally guided in one or more loops or straps 31 arranged at intervals along the guide member 24, 25. .Aliat spring 32 is arranged under'the stra'pZ-BO and securedat one end to the strap by a securingdevice "33. The free end of the spring 32 bears against the tape passing under thestrap andis serrated or toothed as at 34 inorderto positively block any retrograde movement of the tape. Tension on the spring 32 is regulated by a thumb screw 85mounted in the'strap 30, the screw in turn being held against rotation byone end of a bow spring 36.

Arranged in horizontal position and carried by the vertical section 25 of the tape guiding unit is a cutter mechanism in the nature of a pairof scissors including astationary blade 37 and a pivotedblade 38, the latter at its free'end being provided with an operating -thumb piece 39 and a coiled contractile spring 40 normally holding the movable blade inthe inactive position shown in the drawings.

To sever the tape, the operator "simply places a finger on the'member 39 and forcibly swings the movable blade 38 to closedposition. Full closing of theblade which might result in the'two blades sticking together is prevented by the engagement of the stud member 41iwith the thumb piece 39.

Secured upon the needleplate'ofthe machine in any suitablemanner 'as by'a thumb screw 42 is a gauge plate 43 including a vertical flange 44- disposed in parallelismwiththe path of travel of the tape and material '45 to which the tape is attached a's' the tapeand material are passed under the needle 46. A finger 47 projecting beyond 'the flange 44 serves to. guide the end of thetape under the ,presser foot 48 and its associated needle.

By virtue of theabove described construction, retrograde movement ofthe tape incidental to cutting thereof, is absolutely prevented, and the tape may be accurately'fed from the floating tape roll at all times.

The construction of the tape rollholder is 1 such that a new roll maybe readily replaced. The entire attachment is 'free from vibration ily bodily'removable from the machine.
